RE: .22 for kids
I have a 7 and 11 year old pair of boys. . . .We started gun safety with BB Guns first, bought a bolt action single shot, one in one shot no mistakes. We have now moved up to another single shot but a .22, Russi, Rossi ? They run just over $100 and come in a number of calibers and can include a 2 barrel offering, I got the .22 and 20Ga one. Break open like a shot gun, so once again no supprises, one shell in one shot open and do it again.
As a bonus, I use .22 shorts in it to shoot Armadillos in my yard at night. Little laser pointer above the sights works out pretty good.
